BRICK-PRESS.

SPECIFICATION forming part of Letters Patent No. 650,139, dated May 22,1900.

Application filed October 23, 1897. Serial No. 656,204. on model.)

To all whom it may concern.-

Be it known that I, WILHELM SURMANN, a subject of the German Emperor,residing at Meiderich, near Ruhrort, Rhenish Prussia, Germany, haveinvented new and useful Improvements in Brick-Presses, (for which I haveobtained Letters Patent in the following countries: Germany, not yetissued, dated June 3,1896; Austria, No. 4:6/3,985,dated Ootober 10,1896; France,No. 257,563,dated June 25, 1896; Hungary, No. 6,495, datedJuly 6, 1896; Belgium, No. 122,215, dated June 29, 1896; Russia, not yetissued, dated June 10, 1896; England, No.15,753, dated July 16, 1896,and Luxemburg, No. 2,768, dated March 3, 1897,) of which the followingis aspecification.

My invention relates to dry-stuff brickpresses; and its objects are thefollowing: First, to give from above and from below an equal andsimultaneous pressure on the stuff in the mold; secondly, that beforeexerting the effect of this pressure an intermediate press-plate can beshifted away from the upper die or piston for a determined period, so asto get a lift-space for said upper pistons and the bridge-piece to whichthey are fixed; thirdly, to provide means for effecting a quick lift ofsaid upper pistons out of the mold 'in order to insure the quick pushingout from below of the pressed bricks by the lower pistons and therefilling of the mold immediately after a quick downward return of saidlower pistons. In order to elfect these purposes, I construct the presswith a special system of cams, eccentrics, and levers which actuate thelower pistons upward forpushing out the brick and downward for therefilling of the mold by moving downward the crossbeam supporting thepistons on two side columns on which it slides, and I construct anotherspecial system of cams, eccentrics, and levers actuating quickly and inthe right moment the upper pistons independently from the toggle-leveraction of the press and within the framing of the pressing cross-head,and I arrange a third set of cams and levers actuating the intermediatepress plate in shifting it from or inserting it between the bridge-pieceand the pressing cross-head. The filling of the molds is done in theknown manner by a sliding plate moving under a filling-trough with atransporter in it and being actuated by a cam, disk, and rod. The finalpressure is then given by the toggle-lever arrangement simultaneouslyfrom above and from below on the pistons, transmitting it to the stuffin the molds.-

The accompanying drawings represent the press, in which- Figure 2 showsa vertical section of the machine. Fig. 1 shows a front view of thesame;

and Fig. 3 is a detail view of the machine,-

partly in vertical section, showing the opera tion of the bars 2.

The motion is transmitted to the press by the pulleys a a, driving a setof gear-wheels b c d e, turning a crank-axlef. Connectingrods 9 actuatecrank-levers h, swinging on an axle 71, fixed in the standard frame A.Links 1' and it, connected to lever h by bolts 11 and k and to avertically-movable crossbeam 'n and a vertically-guided cross-head m bybolts 1 and m, respectively, form a system of toggle-levers, giving tosaid crosshead m and to cross-beam at opposite equal and simultaneousoscillation, as is easily understood in following the dotted lines onFig. 2, which show that the centers of bolts '6 and; k reach the extremepositions of their path when they both arein the same vertical line withthe center of axle 7L2.

The vertical oscillations of cross-beamn are transmitted by two siderods 0, guided in the boxes A of frame A, to the lower cross-beam p,which takes a seat on the nuts 0 at the lower ends of rods 0 and ismovable This cross-beam p upward on the latter. carries the lowerpistons g, which enter into a fixed table 6 of the frame and are capableof moving up and down in the molds 3, contained therein.

The link-bolt m presses down the cross-head m in its guides between theframe-standards simultaneously with and in the same measure as bolt Z islifting. The upper pistons r,

.fixed to the cross-heads bridge-piece a and tion shown in dotted linea't'o ydisengaging thereby the bridge-piece a. The latter, with itsupper pistons r, is then free to be lifted rollers c at theend'sfo'flevers d, turnin'g'on'i sald axle 01;, and reaching with theirotherends and roller (1 held thereon, into a suit able pocketof lowercross-beam p,lift ing the latter quick-1y away Ifrom the nuts 0 on therods 0, and thereby lifting said lower pistons I q, standing thereon, toa height such that the top surfaces of the pistons g exactly. come-flush with thesurfaceof the table e'. Their placed above the table a,and closed afterwardby the upper back plate of box h. As soon as thefilling-box it has then returned intoits" original position (shown inFig. 1) the bridge-pieced, holding the upper pistons termediatepress-plate v is then moved into its vertical position by the connectionof rod a and lever u with roller u, worked by cam t. Then thelever h ispulled downward by connecting-rod g and crank f, and when they approachtheir lowest point increasing pressure is exerted upon the two pistonsrand q si multaneously and with equal force. It is obvious that by thearrangement of' the insertion of press-platen it is rendered possible toaccelerate the downward as well as the ascending movement of the upperpistons'independently from the regularcmovemerits-of the toggle-leversystem without un- -coupling the latter.

By using the double-acting and opposite movement away from each other ofboltsl and m'tlie frame A is relieved from thepress- "in'g strainpandthe rods 0 and the strong cross-beams "n and 19 take up the whole thrustof the pistons, and the relatively-small distance traveled by said boltsgives a favorable toggle-lever pressurefor both the upper and lowerpistons atoneand the same time. c l y I am, aware that toggle-leverbrick-presses have beenused before, andl do not claim such a pressbroadly; but

WhatI' do claim, and desire to secure by Letters Patent, is
